Squinches
Extracted from the Wikipedia article Squinch.
Squinches originated in the Sassanid Empire of Ancient Persia, and have remained in use across Central and West Asia into modern times. From their Sassanid origin, they influenced Islamic architecture and were inherited by Georgian and Armenian building traditions. Domes built in the Roman-influenced world utilised separately-evolved construction methods, notably the pendentive, which performs a similar function.
